Guys,
How are you doing?
The idea proposed by Andres and Javier sounds great :)!

That's because of the GIL implementation and how python handle threads and
IO interrupts and other CPython internals...

Multiprocessing is really good and has an API similar to the threading
module(not trivial), also is easy to share data, objects or whatever you
want between process using the Queue module. I think that concurrency using
multiprocessing is "painless" because you dont use many LOCKS in your code.
I hope this mail help you!
